Description

FOLDABLE SWIMMING FLIPPERS

More particularly, the present invention relates to a folding swim flippers having a folding structure that can be folded while being stored and stored in a reduced volume, and can be used while being used.

Swim flippers are usually used to speed swimming in the water. The principle of the swimming flippers is that if a swimmer wiggles the webbing up and down in a state where the swimmer is in a pin-up state, the webbing pushes the water backward, .

However, the swim flippers have a problem that the swing flap is formed wide on the front of the foot wear part in order to increase the propulsive force, so that it is difficult to walk outside the water, not in the water, and not easy to store or transport.

Accordingly, since Korean Patent Laid-Open No. 10-2013-0066475 (Patent Document 1, published on 2013.06.20.) Has a fixed length, it is easy to purchase both short flippers and long flippers, so that the economical burden is great. It is difficult to change the length of the flip according to the skill and the purpose of the user. Therefore, in order to solve the problem that a large inconvenience occurs, Length adjustable flippers which can be used both as a conventional short flippers and long flippers as well as to be used in a range of lengths between them.

Korean Patent Laid-Open Publication No. 1997-0068930 (Patent Document 2, published on November 11, 1997) has the same shape and function as the flippers in water, but when walking, the webbing portion and the swallowing portion When the webbing is separated, it is reassembled with the link member at the time of walking and fixed by the restoring force of the rubber band when the webbing portion is raised. When the webbing is to be used, it is inserted into the fastening hole formed at the swinging portion and the webbing portion with the fastening pin, 'A flippers that folds the underwater equipment webbed' that is configured to be

As described above, the flippers of the related art can solve the problem of having webs of various lengths or the difficulty of walking, but in the case of Patent Document 1, the length can be adjusted, but the complexity When the length is shortened, the frictional force is increased due to the folded portion of the webbing.

In addition, the invention of Patent Document 2 does not provide a function of fully folding and fixing for the purpose of storage but also rotatably engages with the link member. Therefore, when the link member is detached, There is a problem that a partial loss may occur when stored.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a folding swimming flipper having a folding structure that can be folded during storage, stored in a reduced volume, and used for unfolding.

In order to achieve the above object, the foldable swimming flippers of the present invention include a foot wear part;

A webbing portion foldably coupled to the foot wearing portion; A folding unit for foldably connecting the foot wearing unit and the webbing unit; And a flat fixing part fixing the foot wearing part and the web part in a spread state.

Wherein the flat fixing portion includes a lock pin portion provided on one of the foot wearing portion and the web portion with the lock pin being moved back and forth; And a pin coupling part formed on a side of the foot wearing part or the web part where the lock pin part is not formed and the lock pin is inserted to fix the foot wearing part and the web part so as not to be folded .

The folding swimming flippers may include a fixing protrusion formed of a fixing protrusion extending from an opposite end of an end portion of the webbing which is engaged with the foot wearing portion and a fixing hook protruding from an upper surface of the fixing protrusion at an end of the fixing protrusion; And a fixing hook groove bar formed on the bottom surface of the foot wearing section to form a fixing protrusion groove formed on the surface on which the fixing protrusion is positioned when the webbing is folded and a fixing hook groove formed across the fixing protrusion groove, ; &Lt; / RTI >

The folding swim flippers of the present invention having the above-described construction provide an effect of significantly reducing the convenience of storage and transportation by folding and storing the swim flippers while they are being stored, and by allowing them to be used while being spread.
